Physics P1 5.3 Wave properties: reflection. 0.0 / 5 ? PhysicsWavesGCSEAQA Created by: Atlanta and JacobCreated on: 07-06-16 18:52 What is the normal at a point on a surface? The normal at a point on a surface is a line drawn perpendicular to the surface. 1 of 17 How are the angles always measured? Angles are always measured between the light ray and the normal. 2 of 17 What does the law of reflection state? The law of reflection states that the angle of incidence is equal to the angle of reflection. 3 of 17 What is the image seen in a mirror due to? The reflection of light. 4 of 17 What is a flat mirror called? A plane mirror. 5 of 17 What is the ray that goes towards the mirror? The incident ray. 6 of 17 What is the ray that is coming away from the mirror? The reflected ray. 7 of 17 What is the angle between the incident ray and the normal? The angle of incidence. 8 of 17 What is the angle between the reflected ray and the normal? The angle of reflection. 9 of 17 For any reflected ray, what is the relation in size between the angle of incidence and the angle of reflection? They are equal. 10 of 17 What are the features of an image in a plane mirror? The image is the same size as the object, upright, the same distance behind the mirror as the object is in front and virtual. 11 of 17 What s a real image? One that can be formed on a screen because the rays of light that produce the image actually pass through it. 12 of 17 What is a virtual image? One that cannot be formed on a screen, because the rays of light that produce the image only appear to pass through it. 13 of 17 What is the normal? A line drawn perpendicular to a reflecting surface. 14 of 17 What size is the image in a plane mirror? The same size as the object. 15 of 17 **MAKE SURE THAT YOU UNDERSTAND THE DIFFERENCE BETWEEN A REAL IMAGE AND A VIRTUAL IMAGE** **PRACTICE DRAWING NEAT DIAGRAMS TO SHOW REFLECTION IN A PLANE MIRROR AND REMEMBER TO PUT ARROWS ON THE RAYS** 16 of 17 **LOOK UP DIAGRAMS OF THE LAW OF REFLECTION AND IMAGE FORMATION BY A PLANE MIRROR** ** 17 of 17
